Question

Cellular Respiration is amphibolic or exergonic process ?

• A. Amphibolic
• B. Exergonic
• C. Both amphibolic and exergonic
• D. Neither amphibolic nor exergonic

Answer 1

Answer: (C)

Amphibolic and Exergonic

Answer 2

Cellular respiration is a metabolic process that involves the breakdown of organic fuel molecules (like glucose) to release energy. This net release of energy, which is primarily captured in the form of ATP, defines the process as exergonic.

Furthermore, cellular respiration incorporates pathways such as the Krebs cycle (Citric Acid Cycle). The Krebs cycle is classified as an amphibolic pathway because it serves dual roles: it breaks down acetyl-CoA (catabolic function) and also provides intermediate molecules that are essential precursors for the synthesis of various biomolecules like amino acids, fatty acids, and heme (anabolic function).

Since cellular respiration encompasses both the net release of energy and pathways with dual catabolic/anabolic roles, it is correctly described as both amphibolic and exergonic.
